From my own personal enjoyment of this drama I rate it 10/10; it was a perfect example of my favourite character trope, the defective detective. I absolutely loved the chemistry between the two leads, and Tokie-san was such a queen. The narrative was a bit basic, especially compared to other detective dramas, that however is acceptable as I would call this a character driven drama. The music was just a a tad too much overused, however it did do it's job to enhance the emotions of the scene; which reminds me of how it sometimes suddenly cuts from moments of high tension to a completely different scene, which only pissed me off a little. Although this was my second time watching it and it I still enjoyed it immensely, even with all these flaws I was still able to emotionally invest in the characters, and really I think that's all that matters.
